      <description>&lt;P class="lia-align-left"&gt;Dear Srs,&lt;/P&gt;&lt;P class="lia-align-left"&gt;I tried to create a parameter in order to assign for specific class of use in any&amp;nbsp;&lt;SPAN&gt;room a related-.specific value of air flow/ for person taken from&amp;nbsp; a&amp;nbsp; UNI&amp;nbsp;&lt;/SPAN&gt;schedule&lt;SPAN&gt;; but in order to applyi it in Revit, I need to understand how correctly I have to type it between parameters, since, REvit gives me back as uncorrect, syntax. How to create the right funtion to link Text and parameters in this case?&lt;/SPAN&gt;&lt;/P&gt;&lt;P class="lia-align-left"&gt;below the screenshot&lt;/P&gt;&lt;P class="lia-align-left"&gt;&amp;nbsp;&lt;/P&gt;&lt;P class="lia-align-left"&gt;Best regards, thank you.&lt;/P&gt;&lt;P class="lia-align-left"&gt;&amp;nbsp;&lt;/P&gt;&lt;P class="lia-align-left"&gt;Lorenzo Masotti&lt;/P&gt;&lt;P class="lia-align-right"&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="bims2_0-1701700686755.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1300536iC8B93314A80606D3/image-size/medium?v=v2&amp;amp;px=400" role="button" title="bims2_0-1701700686755.png" alt="bims2_0-1701700686755.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If (Nome="Ufficio",11,10)&lt;/P&gt;</description>

      <description>&lt;P&gt;Hello,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;AFAIK, formulas do not work in tags.&lt;/P&gt;</description>

      <description>&lt;P&gt;My apologies for any language barriers.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It sounds like you are attempting to assign a ventilation air per person requirement to an area in the project.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Rooms (found in Architecture tab) do not typically carry this information - Rooms are mainly used for architecture-related parameters&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Spaces (found in Analyze tab) can carry this information. The Space Type parameter brings up Space Type settings, which can be defined with a number of values, including ventilation air:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="robert2JCCH_1-1701982896024.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1302187i1B3C3425F3B88316/image-size/medium?v=v2&amp;amp;px=400" role="button" title="robert2JCCH_1-1701982896024.png" alt="robert2JCCH_1-1701982896024.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="robert2JCCH_0-1701982482518.png" style="width: 600px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1302183i46EBD2CD79A07C2E/image-size/medium?v=v2&amp;amp;px=400" role="button" title="robert2JCCH_0-1701982482518.png" alt="robert2JCCH_0-1701982482518.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Unfortunately, this would mean having to transfer your UNI sheet values into this Space Type Settings format. This can be done manually, with some third-party addins, and with Dynamo. Once done, you would have this for any future projects as well.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;----------------------------------------------&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If you still want to use calculated parameters, you should know that you &lt;EM&gt;cannot&lt;/EM&gt; check string text in Revit parameter formulas. So&amp;nbsp; &amp;nbsp; &amp;nbsp;[if(Parameter="VALUE",A,B)]&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; is not valid.&amp;nbsp;&lt;/P&gt;</description>
